Story about a far-away civilization transmitting a complex message in all directions, containing a software program (“Turing machine”) which ends up creating von Neumann machines with one specific purpose: encoding all the civilization’s knowledge in the form of folded space-time entities. The ultimate aim is to ensure that the universe is not able to erase all that conscious thought has learnt and invented in spite of the accelerated expansion of the universe which is bound to rip apart all its constituents in time (“The universe has no memory”). Along the way, the story delves briefly into Shannon’s information entropy.
